+- **v3.9**：统一记忆架构。Hermes（hermes-lance） + OpenClaw（openclaw lancedb） + 织忆（MemoryWeave SQLite）三系统统一为织忆后端，消除三方记忆孤岛。
+
+### Appendix E: 统一记忆规划（v3.9）
+
+#### E.1 当前状态
+
+三个系统各自维护向量记忆：
+
+| 系统 | 后端 | 向量维度 | 数据位置 |
+|------|------|---------|---------|
+| Hermes | hermes-lance (LanceDB) | 1024 | `~/.hermes/data/lance/` |
+| OpenClaw | openclaw lancedb (LanceDB) | 1024 | `~/.openclaw/data/lancedb/` |
+| 织忆 | MemoryWeave SQLite + CGO | 1024 | `/var/lib/zhiyi/data/memoryweave.db` |
+
+问题：
+- Hermes 和 OpenClaw 各自维护独立记忆，互不共享
+- 织忆无法直接读取 Hermes/OpenClaw 的记忆
+- 牧尘对 Hermes 说的话，OpenClaw 不知道
+
+#### E.2 目标
+
+**单一记忆源**：Hermes 和 OpenClaw 不再各自存储记忆，统一走织忆 API。
+
+```
+Hermes ──→ 织忆 Client (ZHIYI_URL=http://localhost:7821) ──→ MemoryWeave SQLite
+OpenClaw ──→ 织忆 Client ────────────────────────────────→ (同一 DB)
+```
+
+#### E.3 实施步骤
+
+**Phase 1: 配置切换（零代码改动）**
+
+Hermes 和 OpenClaw 的 commit/recall 调用改走织忆：
+
+```yaml
+# Hermes: ~/.hermes/config.yaml
+memory:
+  provider: zhiyi
+  zhiyi_url: http://localhost:7821
+  zhiyi_api_key: ${API_KEY}
+  fallback_to_local: true  # 织忆不可用时回退到本地 hermes-lance
+```
+
+```json
+// OpenClaw: openclaw.json
+{
+  "memory": {
+    "backend": "zhiyi",
+    "zhiyi_url": "http://localhost:7821",
+    "api_key": "zhiyi-dev-key-2026"
+  }
+}
+```
+
+**Phase 2: 双写迁移**
+
+织忆启动时扫描 Hermes/OpenClaw 现有数据并导入：
+
+```bash
+zhiyid --migrate-hermes=/home/muc/.hermes/data/lance
+zhiyid --migrate-openclaw=/home/muc/.openclaw/data/lancedb
+```
+
+迁移完成后，Hermes/OpenClaw 的本地记忆目录标记为只读备份。
+
+**Phase 3: 移除本地存储**
+
+Hermes 和 OpenClaw 移除本地 LanceDB 依赖，纯客户端模式。织忆成为唯一记忆源。
+
+#### E.4 API 兼容性
+
+织忆已完全实现 Hermes/OpenClaw 原有接口的超集：
+
+| Hermes 接口 | 织忆接口 | 状态 |
+|------------|---------|------|
+| memory.save() | POST /api/v1/commit | ✅ |
+| memory.search() | POST /api/v1/recall | ✅ |
+| memory.delete() | DELETE /api/v1/distilled/{id} | ✅ |
+| memory.bootstrap() | GET /api/v1/bootstrap | ✅ |
+| memory.feedback() | POST /api/v1/feedback/* | ✅ |
+
+#### E.5 回退策略
+
+织忆进程宕机时，Hermes/OpenClaw 自动回退到本地 LanceDB（`fallback_to_local: true`）。恢复后自动同步差异数据。

+
+## 2026-05-28: v3.8 锁定 Go + Rust 双二进制
+
+**决策**: 织忆主进程用 Go (daemon + API)，Rust sidecar 负责计算密集型整合（LanceDB/BGE/聚类/衰减）。
+**理由**: Go 的并发模型适合 API 层，Rust 的零开销适合数据引擎。
+
+---
+
+## 2026-05-27: BGE-M3 从 API 迁移到本地 ONNX
+
+**决策**: 使用 BGE-M3 ONNX 模型本地推理，替代模力方舟 API 调用。
+**理由**: 降低延迟 (500ms → 43ms)，去除 API 依赖 (网络被墙)。
+
+---
+
+## 2026-05-26: 零外部依赖策略
+
+**决策**: 所有 Go 功能用标准库实现，禁止引入 gorilla/websocket、go-redis 等外部包。

+# Learnings — 学习成果
+
+> 从项目实施中积累的经验教训
+
+## 技术选型
+
+1. **Go 标准库足够强大** — 零外部依赖策略可行，手写 Redis/SQLite 客户端虽然大但稳定性好
+2. **ONNX 比 vLLM 更适合边缘设备** — RTX 3050 4GB 跑 vLLM 吃内存，ONNX 43ms 推理更实用
+3. **文件图谱比内存图谱更可靠** — 进程重启不丢图数据，JSON 序列化在 10000 节点以下够快
+4. **Rust sidecar 虽然重但必要** — DBSCAN/衰减回归等计算密集型工作交给 Rust 是正确的
+
+## 架构决策
+
+1. **统一记忆 (v3.9) 应尽早实施** — 三系统 (Hermes/OpenClaw/织忆) 各自维护本地 LanceDB 是技术债务
+2. **CO_OCCURS 预取必须持久化** — 内存统计重启丢失，需要写入 Redis/SQLite
+3. **蒸馏质量回溯比精确蒸馏更重要** — 知道"丢了什么信息"比知道"蒸馏了什么"更有价值
